Hypothesis Testing of Mean
System data for a job shop
revealed that the average time spent by a job in the shop was approximately n =
5 working days. A random sample of size five is taken with time spent in the
shop, 3.7, 4.6, 3.9, 4.1, and 3.8. Is the output consistent with system
behavior? (Why?). Construct a statistical test using a level of significance of
alpha = 0.05
